Created attachment 123342 [details] Screenshot of columns. No network usage available! From the release notes, I understood that it should now be possible to show network usage per process. However, in the process table's column list, there is no column for network usage (see screenshot). Please forgive me if I've misunderstood the release notes!
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task. If your issue still happens with the Plasma 6 replacement, please re-open and we can move this bug to the new product, thanks!
